How are people managing nuclear energy so we don't run out of it?

People are managing nuclear energy by utilizing advanced reactor designs that enhance safety and efficiency, such as Generation IV reactors and small modular reactors (SMRs). Additionally, there is ongoing research into nuclear fuel recycling and breeder reactors, which can extend the life of nuclear fuel by reusing spent fuel. Regulatory frameworks and international cooperation also play a crucial role in ensuring the safe and sustainable operation of nuclear facilities, while public awareness and acceptance are increasingly emphasized to support future developments in nuclear energy.
